Overview

Product summary

Review the store description, core capabilities, and common use cases.

Prompt Guard is your essential privacy layer for interacting with AI. As AI assistants like ChatGPT, Claude, and Gemini become integrated into our daily workflows, the risk of accidentally sharing sensitive information—such as API keys, passwords, or Personally Identifiable Information (PII)—has never been higher.

Key Features:

Real-time Detection: Automatically scans your prompts as you type for sensitive data.

Instant Redaction: Allows you to mask or redact sensitive information before it's sent to AI servers.

Wide Platform Support: Works seamlessly with ChatGPT, Claude, Gemini, Perplexity, Poe, and 20+ other AI platforms.

Local-First Privacy: Data scanning is performed locally on your device to ensure maximum security.
